At present, with the rapid development of display technology, various new display products are layered endlessly, in the display field, especially in the OLED (organic light-emitting diode) display field, high brightness is a requirement of the current market for a display panel, when the display panel displays a picture, because the data voltage of the highlight display area is large, the material degradation of the light-emitting device is serious, the VTH (threshold voltage) of the TFT (Thin FilmTransistor ) in the light-emitting device can drift, so that the afterimage phenomenon occurs in the display panel, the light-emitting current is too large due to the writing of the too high data voltage, and the local temperature of the light-emitting device rises too much, so that the VTH drifts more rapidly, and the afterimage is more serious.
In the related art, voltage compensation is performed on all pixels in the highlighted area, so as to adjust the image, and avoid visual defects, but the voltage adjustment is performed on all pixels, so that the processing amount is large, the energy consumption is high, and the material degradation is accelerated.
In the process of realizing the application, the edge of the highlight region of the display panel is generally smooth and regular, the highlight region and the non-highlight region are obviously different, so that a user can see a more obvious residual image boundary when watching a display picture, the appearance of the residual image is obvious, therefore, the edge of the highlight region can be subjected to fuzzy processing to be dispersed or irregular, the user can not see the obvious residual image boundary, the appearance of the residual image is not obvious, only the pixels near the edge are processed, and compared with the processing amount of the pixels of all the highlight region, the processing method is small in energy consumption.
Hereinafter, the technical solutions of the present application will be described in detail by specific embodiments in conjunction with fig. 1 to 13.
In some embodiments of the present application, a method for improving an afterimage of a display panel is provided, as shown in fig. 1, including the following steps:
s1, acquiring a highlight area 1 and a non-highlight area 2 of a display panel, wherein pixels positioned at the edge of the highlight area 1 are first pixels 1-1, and pixels which are close to the first pixels 1-1 and positioned in the non-highlight area 2 are second pixels 2-1.
As shown in fig. 2, a schematic diagram of a display panel is shown, the display panel may be divided into a highlight region 1 and a non-highlight region 2 according to the original voltage of each pixel of the display panel, as shown in fig. 3 and 6, the pixel located at the edge of the highlight region 1 is a first pixel 1-1, and the pixel located near the first pixel 1-1 and within the non-highlight region 2 is a second pixel 2-1; the edge may be defined as a circle of pixels in the highlight region 1 closest to the non-highlight region 2, or may be defined as several circles of pixels in the highlight region closest to the non-highlight region 2, which is not limited in particular; the second pixel 2-1 is any pixel within a few circles of the first pixel 1-1, and can be set according to requirements; the first pixel 1-1 and the second pixel 2-1 are determined to provide a basis for subsequent voltage adjustment.
S2, adjusting partial original voltage of the second pixels 2-1 into a first voltage according to the original voltage of the first pixels 1-1, and distributing or irregularly distributing the second pixels 2-1 subjected to voltage adjustment.
The original voltage of a part of the second pixels 2-1 is adjusted to be the first voltage according to the original voltage of the first pixels 1-1, and the arrangement of the second pixels 2-1 subjected to voltage adjustment is scattered or irregular, as shown in fig. 3 and 6, namely, the pixels near the boundary of the highlight region 1 are adjusted, the original boundary of the highlight region 1 and the non-highlight region 2 is visually disturbed, so that the highlight region 1 and the non-highlight region 2 are not obviously distinguished, as shown in fig. 3 and 6, the adjusted display panel forms a new highlight pixel set 3, a user only sees a blurred boundary visually, and the appearance of the residual image is not obvious; in addition, the method only processes part of the second pixels 2-1, and does not need to process all the pixels in the highlighting area 1, so that the processing amount is greatly reduced, and the energy consumption is low.
The method for improving the afterimage of the display panel is simple and convenient, can effectively blur the visual boundary of the highlight region 1 and the non-highlight region 2, ensures that the afterimage is not obvious in appearance, improves the afterimage phenomenon, and has the advantages of low processing amount, low energy consumption and high user experience.
In some embodiments, step S1 comprises:
s11, acquiring the original voltage of each pixel in the display panel.
The voltage value of each pixel shown in fig. 2 is the original voltage.
S12, determining a highlight display area 1 and a non-highlight display area 2 of the display panel according to a preset highlight voltage threshold value and the original voltage.
The preset highlighting voltage threshold is, for example, 7V, which is not particularly limited; determining an area formed by pixels whose original voltage is greater than or equal to a highlight voltage threshold as a highlight area 1, and determining an area formed by pixels whose original voltage is less than the highlight voltage threshold as a non-highlight area 2; the new highlight pixel set 3 in other figures is also determined according to the highlight voltage threshold, that is, the adjusted pixel voltages are compared with the highlight voltage threshold, and pixels greater than or equal to the highlight voltage threshold are combined into the new highlight pixel set 3, but the possible pixel arrangement at the edge of the set is scattered, and a closed region cannot be formed.
In some embodiments, the number of pixels between the first pixel 1-1 and the second pixel 2-1 is less than or equal to a preset number.
The preset number is, for example, 0 to 3, and is not particularly limited, and when the preset number is 0, the first pixel 1-1 is adjacent to the second pixel 2-1; when the preset pixel is larger than 0, the second pixel 2-1 is within a few circles of pixels of which the first pixel 1-1 is outwards diffused; defining the distance of the first pixel 1-1 from the second pixel 2-1 is to avoid the second pixel 2-1 from being too far from the first pixel 1-1 so that the voltage of the second pixel 2-1 is not visually disturbed by the afterimage boundary even if the voltage is adjusted.
In some embodiments, step S2 comprises:
s21, exchanging the original voltage of the first pixel 1-1 with the original voltage of a part of the second pixels 2-1, so that the voltage of the second pixels 2-1 is a first voltage, the voltage of the first pixels 1-1 is a second voltage, and the second pixels 2-1 with the exchanged voltages are arranged at intervals.
As shown in fig. 3, the second pixel 2-1 is adjusted by exchanging the original voltage of the first pixel 1-1, so that the voltage of the second pixel 2-1 becomes a larger first voltage, the second pixel 2-1 forms the boundary of the new highlight pixel set 3, and the boundary of the new highlight pixel set 3 is dispersed because the second pixels 2-1 with the exchanged voltages are arranged at intervals, so that the visually highlight display area 1 and the non-highlight display area 2 are not obviously different, and the afterimage phenomenon is improved; and because the voltage of the first pixel 1-1 becomes a smaller second voltage, the boundary of the original highlighting area 1 is destroyed, the boundary of the residual image is further blurred, and the residual image phenomenon is improved; and the voltage of the first pixel 1-1 becomes smaller, so that the degradation speed of the material can be reduced, and the afterimage phenomenon can be further improved.
In some embodiments, said exchanging the original voltage of said first pixel 1-1 with the original voltage of part of said second pixel 2-1 comprises:
s2101, performing voltage exchange on a part of the first pixels 1-1 and the second pixels 2-1 adjacent to the first pixels 1-1, and arranging the first pixels 1-1 not subjected to voltage exchange and the second pixels 2-1 subjected to voltage exchange at intervals.
As shown in fig. 4, a part of the first pixels 1-1 and the second pixels 2-1 close to the first pixels 1-1 are subjected to voltage exchange, so that the first pixels 1-1 which are not subjected to voltage exchange and the second pixels 2-1 which are subjected to voltage exchange are arranged at intervals, and compared with the adjustment of all the first pixels 1-1, the method can ensure the edge dispersion of the adjusted new highlight pixel set 3, improve the residual image, reduce the adjustment quantity of pixels, reduce the processing quantity and be more efficient.
In some embodiments, said exchanging the original voltage of said first pixel 1-1 with the original voltage of part of said second pixel 2-1 comprises:
s2102, voltage-exchanging all the first pixels 1-1 with the second pixels 2-1 located in the diffusion direction of the first pixels 1-1.
The diffusion direction is the direction in which the inside of the highlight region 1 points to the first pixel 1-1, and one first pixel 1-1 has only one diffusion direction, as shown in fig. 5, taking the first pixel 1-1 in the lower left corner of the highlight region 1 as an example, and the diffusion direction is shown as the white arrow direction in the figure, that is, the direction in which the 9.1V pixel points to the 7.6V pixel.
All the first pixels 1-1 and the second pixels 2-1 positioned in the diffusion direction of the first pixels 1-1 are subjected to voltage exchange, so that the boundary of the original highlight region 1 can be completely broken up, the visual boundary is unclear, and the afterimage phenomenon is improved; and the processing is more convenient than the random scrambling of the arrangement of the second pixels 2-1.
In some embodiments, two adjacent first pixels 1-1 are disposed at intervals corresponding to the second pixels 2-1 for voltage exchange.
As shown in fig. 9 and 10, the highlight region 1 is a rectangle of 4*3, and two adjacent first pixels 1-1 with 9.3V voltages are arranged on top of the highlight region 1, and when the voltages of the first pixels 1-1 are interchanged, the selected second pixels 2-1 are arranged at intervals, so that the boundary dispersion of the new highlight pixel set 3 is ensured, and the afterimage phenomenon is effectively improved.
In some embodiments, step S2 comprises:
s22, the original voltage of the second pixel 2-1 along the diffusion direction of the first pixel 1-1 is adjusted to be a first voltage, and the first voltage of the second pixel 2-1 is smaller than the original voltage of the first pixel 1-1 and larger than the original voltages of other second pixels 2-1 adjacent to the second pixel 2-1.
The diffusion direction is the direction of the first pixel 1-1 within the highlight region 1, as shown in fig. 6, taking the first pixel 1-1 in the middle of the lower portion of the highlight region 1 as an example, and the diffusion direction is the direction of the white arrow in the figure, that is, the direction of the 9.3V pixel from the 9.1V pixel.
The number of the second pixels 2-1 adjacent to the first pixel 1-1 is plural, and if all the second pixels 2-1 are adjusted, the plural adjusted second pixels 2-1 tend to form a regular ring structure, and the effect of blurring the boundary cannot be achieved; in the embodiment, only the second pixels 2-1 along the diffusion direction are adjusted, so that the arrangement of the adjusted second pixels 2-1 is irregular, the visual boundary is unclear, and the afterimage phenomenon is improved; and the first voltage is set to be smaller than the original voltage of the first pixel 1-1 and larger than the original voltage of the adjacent second pixel 2-1, so that the boundary of the original highlight display area 1 can be desalted, the boundary of the visual afterimage is blurred, and the afterimage phenomenon is improved.

In some embodiments, the number of the second pixels 2-1 corresponding to the two adjacent first pixels 1-1 for adjusting the original voltage is different.
As shown in fig. 11, the highlighting area 1 is a rectangle of 4*3, two first pixels 1-1 adjacent to 9.3V voltage are arranged at the top of the highlighting area 1, and when the second pixels 2-1 corresponding to the first pixels 1-1 are adjusted, the number of the second pixels 2-1 corresponding to the two first pixels 1-1 are different, so that edge tends to be regular when a new highlighting pixel set 3 is formed, and the afterimage phenomenon is further improved.
In some embodiments, the method for improving an afterimage of a display panel further includes:
and S3, adjusting the original voltage of the pixels in the highlighting area 1 to be a third voltage according to a preset frequency, wherein the third voltage is smaller than the original voltage of the corresponding pixels.
The preset frequency may be one pixel display frame interval, and the pixel display frame interval may be an odd frame or an even frame, which is not limited specifically.
As shown in fig. 7 and fig. 8, by intermittently reducing the pixel voltage of the highlight region 1, on the one hand, the user can see the display screen without reducing the voltage by using the visual residue of the human eye, the viewing is not affected, and the arrangement of alternating brightness and darkness can make the visual highlight effect more obvious, so that the user experience is improved; on the other hand, the reserved time is recovered by reducing the voltage to the threshold voltage drift of the TFT in the highlight display area 1, so that the afterimage phenomenon is improved, meanwhile, the degradation speed of the light-emitting device material can be reduced by reducing the voltage, and the service life is prolonged.
In some embodiments, the preset frequency may be a plurality of pixel display frames at intervals, for example, voltage adjustment is performed between two pixel display frames at intervals, and the preset frequency is at most 10 pixel display frames at intervals, so that the situation that the interval is too long, the human eyes form visual residues on the reduced-voltage picture is avoided, and user experience is reduced.
In some embodiments, the third voltage adjustment may be performed for 2 to 3 consecutive pixel display frames, so as to reserve more time for drift recovery, further reduce the degradation speed of the light emitting device material, and improve the afterimage.
In some embodiments, the third voltage is 0 or scaled down according to the original voltage of the corresponding pixel.
As shown in fig. 8, the third voltage is 0, so that the afterimage can be effectively improved, and the threshold voltage can be fully recovered; as shown in fig. 7, the third voltage may be scaled down according to the original voltage of the corresponding pixel, for example, the pixels in all the highlighting region 1 may be scaled down by 50% of the original voltage, so that the drift is recovered, and a certain display brightness is ensured, thereby improving the display effect.
In some embodiments, the foregoing highlight region 1 depressurization processing may be performed at a first preset frequency, the foregoing edge blurring processing may be performed at a second preset frequency, for example, the highlight region 1 depressurization processing may be performed on the pixels of the odd frame, and the edge blurring processing may be performed on the pixels of the even frame, so that the afterimage phenomenon may be cooperatively improved.
In some embodiments, the original voltages of the other pixels except the first pixel 1-1 in the highlight area 1 are adjusted to the third voltage according to the preset frequency, so that the pixels of the continuous frames can be subjected to edge blurring processing, for example, voltages of the first pixel 1-1 and the second pixel 2-1 of the continuous frames are interchanged, so that the edge blurring processing is not disturbed, and the afterimage phenomenon is improved more effectively.
